MEANS FOR HAULING VEHICLES FROM BOGS, SWAMPS, AND THE LIKE.

Application filed January 15, 1925. Serial No. 2,674.

To all whom it may concern:

Be it known that HERCULES CRAFAR, a citizen of the Dominion of New Zealand, residing at Fordell, in the Provincial District of YVellington, New Zealand, has in vented certain new and useful Improvements in Means for Hauling Vehicles from Bogs, Swamps, and the like, of. which the following is a specification.

This invention relates to means employed for hauling vehicles out of swamps bogs and the like.

Means at present employed for the aforesaid purpose include ropes secured to fixed objects and adapted to be wound on to a power driven wheel of a vehicle or on to a drum fixed thereon.

The present invention provides improved vehicle hauling means of the type above mentioned.

According to the invention the improved means comprise a drum or the like adapted to be secured to a vehicle driving wheel and a flanged ring of slightly larger diameter than the drum adapted to encircle and revolve freely about the latter.

Means are provided whereby the drum and the flanged ring may be locked together when desired.

A wire rope or the like secured at one end to the flanged ring is led in the direction in which it is desired to haul the vehicle and secured at its other end to some fixed object such as a tree, stump, post or the like.

The flanged ring and the drum are then looked together by means provided there for and power is transmitted to the vehicle driving wheels, whereupon the latter, not being able to secure a grip in the soft ground of the swamp, bog or the like, will spin or revolve therein and cause the drum to be rotated thereby winding in the wire or rope around the flanged ring and so drawing the vehicle towards the fixed object to which the wire or rope is secured, until firm ground is reached.

By unlocking the flanged ring from engagement with the drum, the former is free to rotate around the latter thereby enabling the wire or rope to be unwound from the flanged ring and removed therefrom.

The drum can be made with lugs or portions for bolting to the wheel, the bolts carrying clips preferably of a triangular shape which engage projections, grooves,

recesses or catches on the flanged ring to lock the latter to the drum.

The drawing herewith illustrates the invention in which Figure 1 is a diagrammatic elevation of the general arrangement.

Figure 2 is a front elevation of a wheel fitted with my invention.

Figure 3 is a side elevation of the same, and

Figure 4 is a cross sectional elevation of the same.

The drum 1 is secured to the driving wheel 2 of a vehicle 3 by means of clips 4, which embrace spokes 5 of the said wheel. The drum has a shoulder 6, and a ring 7 secured to the drum by screws 8. A ring 9 having flanges 1O fits freely on the drum and is retained by the shoulder 6 and the ring 7. Bosses 11 on the drum and bosses 12 on the ring 9 are adapted to be brought into juxtaposition, and bolts or pins 13 are adapted to pass into holes in the said bosses 11 and 12, whereby the ring may be made to revolve with the drum.

A wire rope 14 or the like securedat one end to the ring 9 is paid out in the direction in which it is desired to haul the vehicle, and is secured at its other end to a fixed object, such as a stake 15 shown in the drawing.

The drum 1 being fixed on a driving wheel 2 of the vehicle 3, the ring 9 being locked to the drum, and the rope 1st fixed at its ends respectively to the ring 9 and to the stake 15, power is transmitted to the wheel 2, which thereupon revolves with the drum and ring 9 and winds the rope upon the ring, whereupon the vehicle is drawn towards the stake 15 until firm ground is reached. v

The ring 9 is then unlocked from engagement with the drum 1 leaving the ring free to revolve thereby enabling the rope 1 1 to be unwound from the ring and removed therefrom.

What I do claim and desire to obtain by Letters Patent of the United States of America is y 1. An attachment for power vehicles, comprising, a drum having a hub and a projecting flange, coupling means on the flange for coupling the drum to a drivewheel of a vehicle, a. double flanged ring rotatably sleeved on the hub, a first projecting lug on one face of the drum flange, a second pro- PATENT OFFICE.

jecting lug on one face of one of the ring flanges and positioned to register with the first lug upon rotation of the drum on the hub, and means for interconnecting the 5 lugs to thereby prevent rotation of the ring relative to the drum.

2. An attachment according to claim 1,

an annular ring bolted to the outer end of the hub and projecting beyond the hub periphery, for preventing longitudinal movement ofthe ring.

In testimony whereof I have signed my name to this specification.
